SHIPPING DRUM.

Application led November 20, 1922. Serial No. 602,095.

shipped separate to the user who assemblesV them. In one type ofshipping drum, the

y kl body is crimped or rolled inwardly adjacent the ends to formshoulders which serve as supports for the heads, the heads being lacedin position and a portion of the body beyond sald Shoulder being rolledor turned over to engage a flange formed on the pe riphery of the head.

In the present invention, we provide a drum consisting of aV body havingpreformed rolled edges to receive the head, the

shoulder beneath the head being rolled in the drum by the user after thehead has been inserted. By eliminating the shoulder beneath the head andproviding a substantially flat body, a large number of'bodies may be 90nested in shipping, thus reducing the cost of shipment.

An object of the invention is the provision ofa body having its edgesprovided with seams adapted to be interlocked and being provided withreenforcing hoops, rolled in the body and vertical reenforcementsarranged adjacent each side of the seam.

In Vthe accompanying drawings, we have shown one embodiment of theinvention. In

l0 this showin Figure 1 1s a front elevation of the drum,

Figure 2 is a vertical sectional view,

Figure 3 is asimilar view showing the head about to be placed inposition,

Figure 4 is an end elevation of a number of drums nested,

Figure 5 is a detail sectional view 5-5 of Figure 1,

Fi re 6 is a plan view of a head proon line 5 vide with a supplementaryopening, andV Figure 7 'is a detail sectional view on line 7-7 of Figure6.

' Referring to the drawings, the reference numeral 1 designates the bodyof the drum which,'as -shown,is formed of sheet metal and 1s providedwith curled edges 2 adapted to form an Acme seam. These body por tionsare adapted to be shipped knocked down and nested, as shown in Figure 3of the drawings, and when the drum is to be usedby a shipper, the edges2 are intel-locked and hammered to form a tight joint, as shown inFigure 5 of the drawings. During the manufacture of the drum, the bodyis rolled to form horizontal hoops 3, extending substantially the entiredistance around the drum. These hoops are connected to ver tlcal, rolledportions 4, forming braces on each side of the seam. The ends of thebody portion are turned over, as at 5, and extend substantially parallelto the body portion. The parallel portions may be provided withtriangular shaped cut out portions 6, to permit it to be readilycompressed when the head is placed in position. The head consists of asubstantially circular plate 7 having a peripheral Harige 8.-

'The head and drum are shipped separable. in knocked down condition andwhen lthe drum is to be assembled, the head is sprung lnto positionbetween the turned-over portion and the body and after the head has beenplaced in position, the body is rolled to form a shoulder 9 adjacent thehead and retain it in position. A roll 10 may also be formed in the`flange of the head, the turned over portion 5 and the adjacent portiono! the body, as shown in Figure 2 of the drawings.

In Figures 6 and 7 of the drawings, I have shown a head having asupplemental opening therein. An inwardly extending iange 11 is arrangedaround this opening and the opening is adapted to receive a cover 12,having anupstanding flange 13 at its periphery. This iiange is providedwith a horizontal extension 14, to frictionally engage the head. Thecover is retained in position by sheet metal screws 15.

The advantages to be obtained by assembling a colla sible shipping drumin the method descri ed will be readily apparent. If the shoulders 9 areformed in the drum before it is shipped, it is impossible to snugly nestthe bodies as shown in Figure 4 of the drawings, as the shoulders occupya space and it is necessary to space each pair of bodiesa distance equalto the depth of the shoulder. By providing the turned over edges for thereception of the head and then rolling the shoulder 9 after the head hasbeen inserted, the space occupied by the bodies in shipping ismaterially reduced.

The drumv forming the subject matter of the present invention ismaterially strengthened by the vertically rolled portions 4, formedadjacent the seam. The rolled portions 3 serve as hoops to reenforce thedrum and also provide traction rings on which the barrel may be rolled.This prevents the entire body from coming in contact with the groundwhen the barrel isloaded and is rolled from one place to another.

It is to be understood that the form of the invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing -from the spirit of the invention or thescope of the subjoined claims.

Having thus described the invention, we claim:

1. A knock down drum comprising `a substantially cylindrical sheet metalbody portion having its end turned over to receive a head, said turnedover portion being pro` vided at points spaced from its edge with alinedcut out portions to permit itv t0 be compressed, and a head having aperi heral flange, said lanee being adapted to e re- .ceived between theend of the` body portion to be compressed, a head having a peripheral,

flange, said lange being adapted to be received between the end of thebody portion and the turned over portion, said flange and.

turned over portion, and said body portion adjacent said flange, beingrolledin alinement with said cut out portions to form an outstandingannular bead of substantially semi-circular cross section, and anannular shoulder rolled inwardly from said body portion inwardly of saidhead, said shoulder having a latface parallel to and contacting withlthe inner face of said head.

In testimony whereof, we ailix our signatures.
